PART 1: Dataflow and charts
To validate your data on CEFREF it is important to understand dataflow and what the different charts show.
​
Please answer the following 12 questions, which evaluate your understanding of data flow and the charts.
Stage 1: Input page to Diary page
Headache and painkiller data is transferred to diary page. (Here, Headache pain = moderate, and painkiller taken.)
Stage 2: Diary page to 28-Day Review to 84-Day Review
Headache and Painkiller data are transferred from the Diary page to the 28-Day Review chart.
Total Headache and Painkiller data from 3 consecutive 28-Day periods (e.g. -3 to -1) are transferred to the 84-Day Review chart.
​
The 28-Day Review chart shows Headache and Painkiller-Days in 28-day periods. '-1' is the current period (i.e. the last 28-days). '-2' is the 28-days before that. Here the total number of Headache-Days over the last 28-days (i.e. period -1) is 11.
​
The 84-Day Review chart shows the average data over 3 consecutive 28-day periods (e.g. -3 to -1). Here the average total number of Headache-Days over the last 28-days is 5.
​
*The same dataflow occurs between Month Review and 3-Month Review (not shown).
​
Stage 3: Diary page to Headache- / Painkiller-Free Days chart
Starting from today (11th March), count backwards the number of days when headache / painkiller free. Here there have been 3 Headache-Free Days and 5 Painkiller Free Days.
Stage 4: 28-Day Review to 28-Day Average chart
Day-to-day changes (-1, 0 or +1) in bar totals on the 28-Day Review chart determine direction of trendline on 28-Day Average chart.
​
Subtract YESTERDAY Headache ( or Painkiller) Day total (bottom chart) from TODAY (top chart) total.
​
i.e. Headache, 11 - 12 = -1 (downtrend)
​
i.e. Painkiller, 6 - 6 = 0 (stable)
